SPECIFICATION forming part of Letters Patent No.7705,799, dated July 29, 1902. Application filed April 4, 1902. Serial No. 101.335. (No model.)

To all whom t may concern:

Be it known that I, CHARLES PETER WHIT- TEMORE, a citizen of the United States, resid-y ingat MountVernon,in thecountyofLinn and My object is to provide a monkey-wrench adapted to be operated in the'manner of a bench-vise by means of a handle to apply auxiliary force to the screw 'for tightening the grasp of the jaws upon an object after the movable jaw has been advanced as far as possible by means of the 'ngers of the operator.

My invention consists in the construction, arrangement, and combination of parts, as hereinafter set forth, pointed out in my claims, and Yillustrated in the accompanying drawings, in which-Y Figure 1 is a perspective view of my wrench and shows a vacant space between the two jaws and a metal handle on the shank of the flxed jaw. "Fig 2 is a transverse sectional View of the metal handle and the shank and screw that extend through longitudinalbores therein. Fig. 3 is a longitudinal sectional view ofthe wrench in which the metal portion of the handle is covered with Wood. Fig. 4. is a transverse sectional view of a tang on the end of the shank of the fixed jaw, a screw connected with the slidable jaw, a metal handle, and a wooden cover on the metal handle.

The numeral 10 designates the fixed jaw, and 11 the shank that extends at right angles from thejaw upon which the movable jaw slides. The end portion of the shank terminates in a tang 12, adapted tobe extended through a bore in the handle and shoulders on the end of the shank at the inner end of the tang to abut against the inner end of a handle ttedand fixed on the tang. `The sliding jaw` 13 is tted on the shank 11 and provided with a screw-seat 14c in a common way. A screw 15 is extended into the screw-seat 14., and 16 is an enlargement at the end of the screw, provided with perforations 17 to admit a nail or end of a `handle 19 has a longitudinal bore 20, through which the tang 12 on the end of the shank 11 extends, and 2l is a bore through which the stem 18 extends. 22 is a metal washer fitted to the end of the handle 19 and iixed thereto by means of a screw 23, that extends through a perforation in the Washer and into the end of the tang 12 or in any suitable way. A nut or head 2a is fixed on the end of the stem 18 and provided with transverse bores 25, adapted to admit a straight bar to be inserted to serve as a handle 26 for rotating the screw 15 and operatingthe Ysliding jaw 13 iu the manner of a bench-vise for gripping an object between the two jaws as required for holding the object securely.

In the modified form,` as shownin Figs. 3 and 4c, the enlargement 16 of the screw 15, as shown in Fig. 1, is omitted and the metal portion of the handle adapted in size and shape to be concealed with a tubular `wooden cover 27.

It is obvious the size and Weight of a wrench thus constructed mayvary as desired.

Having thus described the construction,

functions, and arrangement and combination of all the parts, the practical operation and 'advantages gained in the use of my invention will be readily understood by persons familmeans for securing the screw in the handle,

arranged and Acombined to operate in the manner set forth for the purposes stated.

2. In a monkey-wrench, a jaw having a fixed ICO ment and a handle fitted and fixed on the tang to abut against the end of the shank, arranged and combined to operate in the manner set forth for the purposes stated.

3. A monkey-Wrench comprising a j aW having a shank that terminates in shoulders adapted to abut against the end of a handle and a tang adapted to project through a bore in a handle, a slidable jaw on the shank,va screw-seat in the slidable jaw, a screw fitted in the screw-seat and terminating in a stem, a metal handle having a longitudinal bore to admit the stem and a parallel bore to admit the tang, a head on the end of the stem provided with transverse bores and means for fastening the handle to the tang on the end of the shank of the fixed jaw, arranged and combined to operate in the manner set forth for the purposes stated.

4. A monkey-wrench comprising a jaw having a shank that terminates in shoulders to engage the inner end of a handle, a tang adapted to project through a bore in a handle, a slidable jaw on the shank, a screw-seat in the slidable jaw, a screw tted in the screwseat and terminating in a stem, a metal handle having a longitudinal bore to admit the stem and a parallel bore to admit the tang, a head on the end of the stem provided with transverse bores, means for fastening the handle to the tang on the end'of the Vshank of the fixed jaW and a wooden cover on the metal handle, arranged and combined to operate in the manner set forth for the purposes stated.
